STEP 3:
PREPARE AND INSTALL CABINET
1. Slide chassis from cabinet. Refer back to Step 1 of
Window Mounting section.
2. Place cabinet into opening with bottom rail resting
firmly on bottom board of wooden frame.
3. Position cabinet to achieve proper slope for water
removal. (See Fig. 5.)
4. Secure bottom rail to wooden frame with two large
wood screws 1″ (2.5 cm) long using the two holes in
the bottom of the channel resting on frame. (See
Fig. 6.)
Refer to Step 5 of Window Mounting section for
assembly of support brackets. A wooden strip nailed to
the outside wall should be used in conjunction with sill
support angle brackets. (See Fig. 7.)
5. Screw or nail cabinet wooden frame using shims, if
frame is oversized, to eliminate distortion. (See Fig.
8.) Remember to maintain proper slope, as described
in Step 3.
6. Install chassis into cabinet by following all directions
in Step 9 of Window Mounting section.
OPTIONAL:
Caulking and installation of trim on interior
wall may be done. You can buy wood from your local
lumber or hardware supply. On the outside, caulk
openings around top and sides of cabinet, and all sides
of wood sleeve to the opening.
NOTE:
See Fig. 11 of Window Mounting Instructions for
bottom rail seal location.
NOTE:
Check that air
conditioner is tilted back
about 1-1/2
″
to 1-5/8
″
(3
°
to 4
°
downward
toward the outside). If,
after proper installation,
condensation does not
drain from the overflow
drain hole during normal
use, adjust slope.
MASONRY CONSTRUCTION
1. Cut or build a wall opening in the masonry wall
similar to the frame construction (refer to Step 2 of
Thru-The-Wall Installation for wall thickness greater
than 8
½
″).
2. Secure cabinet in place using masonry nails or the
right masonry anchor screws. (Another way to do this
is to build an in-between frame of 2x4’s as shown
in step 2 of Thru-The-Wall Installation but make it
double framed on either side and install between
masonry wall opening and cabinet. Frame must be
securely anchored to masonry wall opening.) This
way gives very good louver clearance on either side
of the cabinet.
3. Install a lintel to support masonry wall above
cabinet. Existing holes in cabinet can be used and/
or additional holes can be drilled to fasten cabinet
at various positions. Be sure that side louver
clearance is in accordance with Step 1 of Masonry
Construction.
4. Install exterior cabinet support brackets as shown in
Step 3 of Thru-The-Wall Installation. Caulk or flash
if needed to provide a weather-tight seal around top
and sides of cabinet.
5. To complete installation, apply wood trim molding
around room side projection of cabinet.
NOTE: After installing, make sure the air conditioner is
tilted 3-4° to the outside to allow water drainage and
perfect cooling efficiency.
